SPECIFICATION forming part of Letters PatentNo. 627,871, datedl une 2*?, 1899.

l Applioationrled May 5,1898. Serial No. 679,861. (lilo model.)

To a/ZZ whom, t may concern):

Be it known that I, THOMAS J. MCBRIDE, a subject of the Queen of Great Britain, residing at Toronto, in the Province of Ontario and Dominion of Canada, have invented new and useful Improvements in Harvesting-Machines, of which the following is a specification.

My invention relates to cutters and cutterbars of mowing or harvesting machines; and its object is to provide an improved construction of the same which shall possess superior advantages with respect to eihciency in use.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a detail elevation of a nger-bar, finger' or guard, and ledger-plates constructed according to my invention, the knife being removed. Fig. 2 is a plan view. Fig. 3 is a partial longitudinal section, the knife being in place.

Fig. 4 is a similar View of a modified construc-v tion. Fig. 5 is a plan View showing a series of knives or cutters.

In the said drawings the reference-n umeral 1 designates the finger-bar of a mowing or harvesting machine provided with the usual ngers or guards 2. Formed in the upper side of these fingers or guards -are curved slots or recesses 3, and secured to the fingers are ledger and Wearing plates 4 and 5, which pro! ject over said slots, as shown. The wearplates are secured to the fingers at suitable distances from each other.

The numeral 6 designates the cutter-bar,

-inclined line from the front or point to the rear end,while the other side,at a point between the front and rear ends, is cut away or inclined rearwardly at a reverse angle on the line 10,

vas shown clearly in'Fig: 5.

The numeral 12 designates the rivet-holes of the knives or cutters, so located that one of them when the sections are in place will be 5 5 at or nearly in line with the point 13 formed by the cut-away portion of the next adjoining knives or cutters.

y I prefer to form the knives or cutters, near their inner ends, with av depression 14, form- 6o ing an oset l5'on the under side, (see Fig.

3,) and in this offset I form the rivet-holes. The numeral 16 designates the rivets passing through said holes.

The fingers or guards are formed with laterally-extending puds 17 at each side and in close proximity with the front end of the slot or recess 3. The Object of these puds is to prevent the fingers from sloughing sidewise 4in event of the bolts holding them to the fin- 7o ger-bar becoming loose. By reason of the curved slots or recesses in the fingers or guards there will be but a limited contact-surface between the cutter-bar and cutters and the ledger and wearing plates, thus greatly rel by stam ping or otherwise at the/time of manufacturing the knives or cutters. In my construction I also dispense with the usual clips secured to the finger-bar and projecting over the knives or cutters, thereby preventing clogging from .theout grass or grain, which is a serious defect with the ordinary construction of cutting-machines.

Havingthus fully described my invention, what I claim is- In a mowing, harvesting or similar machine, the combination with the finger-bar having vfingers provided with puds projecting sidenesses.
